Abstract
The structure of the nose consists of bone and cartilage. The bony part is made up of the nasal bones, the ascending processes of the superior maxillae and the perpendicular plate of the ethmoid and the vomer. The cartilaginous portion, which is the principal support of the tip of the nose, is formed by the quadrangular cartilage that fits into the vomer and the perpendicular plate of the ethmoid. It has a free edge at the lower portion, where it fits into the columella. The triangular cartilages are placed just below the nasal bones and extend downward almost to the alar cartilages. The small space that occurs between the triangular and alar cartilages is the weak spot in the dorsum of the nose. It is at this point that the depression occurs when too much of the septum is resected, as here the septal cartilage alone is responsible for support
